Electronics play a crucial role in enhancing our quality of life through various advancements. Technologies such as Artificial Intelligence (AI), wireless networking, machine learning, and the Internet of Things (IoT) have significantly boosted the production of electronic devices. These devices, often taken for granted, have revolutionized communication and automation. As technology progresses, PCB assembly manufacturers are pivotal in advancing both PCB and PCBA technologies.
PCB Assembly involves soldering electronic components onto a bare PCB (Printed Circuit Board). A PCB is an electronic circuit board where components are mounted to perform specific functions. Components in PCB assembly are classified into passive and active types. Passive components do not amplify signals, while active components can enhance an input signal. PCB assembly can be performed manually or through automated machinery, with automated equipment preferred for its efficiency and reliability. There are two main types of PCB assembly: PTH (Through Hole) and SMT (Surface Mount).
The demand for smaller, lighter, and more durable devices has driven changes in PCB assembly processes. Since the 1950s, PCB assembly has evolved into two primary techniques: Through Hole Technology (THT) and Surface Mount Technology (SMT).
THT involves inserting component leads through pre-plated holes on the PCB to connect its layers. An automatic insertion machine places the components, followed by wave soldering where the PCB is exposed to a solder wave. THT components include axial lead (with leads along the component’s axis) and radial lead (with leads perpendicular to the axis).
SMT uses solder paste to mount components directly onto PCB pads, allowing for tighter spacing and miniaturization of devices. Despite its advantages, some applications still require THT or mixed techniques.
Solder paste is applied to the PCB using a screen printing technique. Lead-free solder paste, like SAC (Tin, Silver, and Copper alloy), is commonly used.
Automated machines place components on the PCB based on programmed specifications.
The PCB is heated in a reflow oven to melt the solder paste, then cooled to cure the solder.
AOI machines perform accurate inspections to detect defects.
Electrical testing methods, such as in-circuit testing (ICT) and flying probe testing, identify faults in the assembly.
Address shortages by qualifying alternative parts and suppliers. China’s abundant material resources make it a strategic choice for PCB assembly.
Ensure adherence to quality standards, such as maintaining proper reflow temperatures.
Focus on optimizing equipment efficiency and reducing setup times to enhance overall capacity.
Excess solder can create bridges between pads. Solution: Adjust paste volume and thermal profiles.
Misplaced components can lead to failures. Solution: Ensure uniform solder paste and accurate machine programming.
Solder may fail to wet contact pads due to oxidation. Solution: Maintain cleanliness and control solder paste conditions.
Components may stand on one end due to uneven soldering. Solution: Optimize temperature profiles and stencil designs.
